Abstract

Iron is a very important element in the biosphere and in material technology. Labeling and tracing methods in connection with the sensitive AMS method offer therefore a wide field of applications for ⁵⁵Fe. We have used a TOF system with channel plate detectors and a Bragg ionization chamber which yields Z and E information. In conjunction with a Wien filter behind the tandem, a significant reduction of neighbouring Fe isotopes was achieved resulting in a sensitivity of about 8 × 10^-13 for ⁵⁵Fe/Fe in a first measurement, corresponding to an activity of about 0.1 Bq in a 10 mg sputter target. The stable isobar ⁵⁵Mn did not contribute as we could not observe Mn^- in our system.
